摘要： A tensioning or guide rail for a chain drive, in particular for a chain drive of an internal combustion engine, comprises two spaced-apart contact sections and one non-contact section arranged therebetween, the contact sections each having a sliding surface which is adapted to be brought into contact with a chain, and the non-contact section interconnecting the two contact sections as a support structure. Such a rail is to be configured such that the installation space available can be utilized more advantageously. To this end, the support structure of the non-contact section comprises an opening extending continuously from a front to a rear of the tensioning or guide rail and separating the contact sections provided with the sliding surfaces. The invention also relates to an endless drive of the type in question.

摘要： A guide rail or a tensioning rail for a chain drive of an internal combustion engine, comprises two separate sliding elements associated with the same span of the chain drive and arranged on a support, the sliding elements having a sliding surface that exhibits a convex curvature in the direction of movement of the chain. This kind of rail is to be improved with respect to its producibility and its tensioning and guiding effect. The angle bisectors of the two opening angles of the two convex sliding surfaces extend relative to each other at an angle other than 0°, the sliding elements being attached to the support as separate modular components. Kits for a guide rail and a tensioning rail as well as a chain drive are provided.

摘要： A chain drive for an internal combustion engine comprises a driving sprocket and at least one driven sprocket, a drive chain coupling the sprockets to each other, and at least one guide rail and/or one tensioning rail for guiding and/or tensioning the drive chain. At least the guide rail and/or the tensioning rail comprises at least two slide elements, arranged at a non-guided distance from one another for contacting the drive chain, such that at least two slide elements are arranged in at least one span of the chain drive. In at least one span, the ratio of guided chain length to non-guided chain length is smaller than 1. Such a chain drive is to be improved with respect to its vibration characteristics. To this end, the sum of the two non-guided lengths of the drive chain between a slide element and the respective nearest sprocket is, in at least one span, which is in contact with a guide rail and/or a tensioning rail with at least two slide elements arranged at a non-guided distance from one another, smaller than 0.5 times the total length of the respective span.

摘要： A link chain has alternating inner and outer chain links connected by a chain articulation, having a direction of motion, wherein each inner chain link has at least one inner plate, and each outer chain link has at least two outer plates and two chain link pins connecting these plates, each pin being rotationally fixed in a pin opening of the associated outer plate and extending through a link opening of the associated inner chain link to form a chain articulation. The inner and/or outer chain links have plate backs contactable with a tensioning rail or guide rail. A forward region of the plate backs in the direction of motion of a part of the inner and/or outer plates extends at an angle to a plane projected between the center lines of the pin openings or link openings. The vertex of the angle points away from the direction of motion.

摘要： A valve unit for a tensioning device of an endless drive is provided, in particular a chain drive of an internal combustion engine, with a carrier plate having an underside forming a contact surface and an upper side which can be faced towards a pressure chamber of the tensioning device, and a valve body which is guided in a receptacle movably relative to the carrier plate for opening and closing a valve seat of the tensioning device. Such a valve unit is to be simplified and more cost-saving. The receptacle is formed by the carrier plate and a suspension device is provided in the region of the receptacle on which the valve body is suspended from the carrier plate in a lowermost position. The carrier plate is horizontal in the non-installed state of the tensioning device, such that the valve body projects downwardly out of the receptacle and is movable upwardly by at least the opening stroke. The invention relates to a corresponding hydraulic tensioning device.
